Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, a kind of new type solar energy thermal storage heating device, there is the main house body of a double-layer structure, described main house body comprises roofing insulation 15, roofing construction sheet 16, air-supply multivane mouth 11, return air flame plate mouth 12 and exterior window 13, also comprise roof sunspace 2, heat preservation sandwich layer wall 3, breeze fan 4, air delivery duct 5, air-return duct 8 and single-glass outer cover 9, described roofing insulation 15 is arranged at above roofing construction sheet 16, roof sunspace 2 is fixed by the roof sunspace support 1 being arranged on roof surface, the bottom of described roof sunspace is provided with air delivery duct 5, its top is coated with single-glass outer cover 9, roof plenum chamber is located at the side of roof sunspace, the breeze fan 4 be connected with air delivery duct is included in described roof plenum chamber, be arranged on the screen pack 7 on air delivery duct and check-valves 6, the air-return duct communicated with roof sunspace is provided with inside the facade wall of main house body opaco, return air flame plate mouth is opened on air-return duct, for indoor return air is introduced air-return duct, the facade wall arranged outside of the opaco of main house body have communicate with air delivery duct there is better bubble-tight heat preservation sandwich layer wall, heat preservation sandwich layer wall is connected with air-supply multivane mouth.
Heat preservation sandwich layer wall 3 in this device should ensure that its air-tightness prevents air from leaking and affects heating effect, by design exterior-wall heat insulation sandwich wall, first hot blast in roof sunspace is sent into heat preservation sandwich layer wall, hot-air flow from heat preservation sandwich layer wall top on earth portion time, have partial heat by heat convection mode, exterior wall outer surface is transmitted to indoor and outdoor wall inside indoor, and all the other heats will send into indoor with hot-air, thus realizes heating on daytime; Because wall heat transfer exists late effect, slowly can import indoor at night, simultaneously because interlayer outer surface is heat-insulation layer, therefore most of heat will import indoor into, thus can make full use of exterior wall heat storage capacity, reduce passive solar house temperature fluctuation situation.
As shown in Fig. 2 enhanced heat exchange collecting plate structural representation, in order to the not high problem of the collecting efficiency overcoming existing roof sunspace further, apparatus of the present invention also comprise enhanced heat exchange collecting plate 10 and hole 14, described enhanced heat exchange collecting plate is the sheet iron being coated with solar energy heat absorbing coating, enhanced heat exchange collecting plate is positioned at the inside of roof sunspace, and roof sunspace is divided into upper and lower two independently spaces; Described porous nickel is opened on enhanced heat exchange collecting plate.
Utilize solar energy heat absorbing coating to carry out plated film to tagger, improve the solar heat absorptivity of collecting plate; Tagger carries out linear cutter after to plated film, the requirement of ventilating according to design, optimizes vent aperture area and air vent is arranged; Meanwhile, forming protruding sunshade surface with sunlight direction vertical plane, this convex surfaces not only can play to keep the sun off and be irradiated to roof outer surface, forms external force simultaneously and improves air turbulence degree realization strengthening heat convection.
Sunlight is irradiated on enhanced heat exchange collecting plate through single-glass outer cover, roof thermal-arrest sunspace is divided into upper and lower two independently spaces by collecting plate, and provide rising passway for bottom heated air, after hot-air heats up, inner air natural layering, the hot-air assembled enters accumulation of heat ventilating and thermal insulating sandwich wall passage by air delivery duct through filter screen and check-valves at the top of thermal-arrest sunspace by breeze fan, a part of heat stores in construction wall by convection current and heat transfer, another part heat is sent into indoor by hot air cleaning from room top supplying air multivane mouth, hot-air reduces gradually in indoor temperature and constantly declines, bottom room, again cold air is evacuated to roof thermal-arrest sunspace by air-return duct through return air flame plate mouth, complete the circulation of whole air.By the construction wall heated, because heat transfer postpones, night just progressively by the thermal release that stores to indoor, this integrated system not only achieves continuous heating on daytime, achieves again and heats night.
The present invention is also provided with automatic tee air-valve, self-operated type ventilation ball and automatic control system in roof plenum chamber, described automatic tee air-valve communicates with the side exhaust duct of roof plenum chamber, get rid of waste heat for controlling side exhaust duct, self-operated type ventilation ball is communicated with the top between roof Yanguan Pass.
During summer operation, owing to being provided with temperature sensor in roof plenum chamber, if temperature sensor detects the stable limiting temperature close to fan operation in plenum chamber, then by controlling automatic tee air-valve, open side exhaust duct, and be communicated with the self-operated type ventilation ball of headroom between Yanguan Pass, under hot pressing and outside wind pressure acting in conjunction, self-operated type ventilation ball just can realize the aeration-cooling of roof sunspace without the need to power consumption, thus solves top room over-heating in summer problem.
The above is only embodiments of the present invention; again state, for those skilled in the art, under the premise without departing from the principles of the invention; can also carry out some improvement to the present invention, these improvement are also listed in the protection domain of the claims in the present invention.
